CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 495,159, dated April11, 1893.

Application filed October 31,1892. fierial No. 450.539. (No model.)

- by declare the following to be a full, clear, and

exact description of the invention, such as V will enable others skilledin the art to which it ICI appertains to make and use the same.

My lnvention relates to certain new and useful improvements in carcouplings and is designed for use upon either passenger or freight cars;and. it consists mainly-in the combination of a specially constructedleverarm and a locking pin, as will be hereinafter described andspecifically claimed.

In the accompanying drawings, Figure l is a perspective view of myimproved car coupling, and showing a portion of a passenger car with thecoupling attached thereto. Fig.

2 is a top plan sectional view of a drawhead, a lever arm and a lockingpin. Fig. 3 is a perspective view of a portion of afreightcar, showingmy improved coupling attached thereto; and Fig. at is a perspective viewof a locking head, a lever arm and a locking-pin,

showing the general construction of the same.

A in the drawings represents a drawhead which may be of any suitableconstruction, but the construction shown is deemed preferable; B alocking-head and O a lever-arm forming a part of the locking-head, thesaid locking-head having a thinned and laterally expanded lever armportion e and between the head proper and the lever arm portion upperand lower vertical shoulders are formed; said locking head being pivotedin the drawhead by means of a pin D in rear of said shouldersasshown.Thislockinghead swings horizontally on its pivot, and in case of asudden jam the shoulders by abutting against the ends of the drawheadproper, will relieve the pivot pin and saveit from being broken.

The locking-head is also constructed with a wedge shaped end portion Etapering toward the back, and an expanded portion 6.

F represents a locking pin which passes vertically through the drawhead.This pin is constructed with a recess G, the larger portion of said pinpassing through an upper plate of the drawhead, and the lower thinportion b of the pin passingthrough the lower plate of the drawhead andextending some distance belowthe same. The upper end of the pin isprovided with a head or projection d. This bead rests upon the upperface of the drawhead when in normal position. The lower end of the pinis provided with a bottom plate portion f,and to this is secured one endof a chain connection H. The upper end of. this chain connection issecured to the lever I, the said lever being pivoted in the car platformJ. i This lever is approximately L- shaped in form, and has its upperend rigidly secured bya catch K when the operator desires to retain thepin in a raised position.

In Fig. 3 I have shown my coupling attached to a freight car, it beingsubstantially the same in construct-ion as that shown in Fig. 1, exceptthat instead of attaching the As the lever arm is swung backward whenthe locking head is being closed, the point of the wedge formed upon theend of the lever arm passes under the shoulder or recess G, therebyraising thelooking pin; and by a continued downward movement of thelever arm the pin is raised until it is high enough to permit of thelever arm passing beneath it into the recess behind the pin. The pinbeing unsupported after the passage of the lever arm, returns to itsnormal position, thereby locking the lever arm. The pin may be releasedat any time by operating the hand lever I and therebyv raising thelocking pin to its proper height, allowing the lever arm to pass belowthe recess, and the pin may be retained in that position to prevent thecars coupling during the operation of switching, or for any otherpurpose, by placing the hand lever in the catch K. The same result canbe obtained by operating the bell crank lever I attached to the freightcar, by means of which the locking pin may be raised to uncouple cars.To retain the locking pin in a raised position, the bell crank lever ispulled cal locking pin F comprising an end portion toward the angleplate M, the lever N resting f, a-thin portion 19, a thickened portion,a upon the same, thereby preventing the lockhead or projection d,substantially as deing pin from returning to its normal position.

What I claim as my invention'is scribed.
